From: Identification of subject-specific responses to footwear during running
Input relevance evaluation of the machine learning models (subject explanations) trained for footwear classification task. (A) Mean ground reaction force (GRF) pattern including mediolateral (GRFML), anteroposterior (GRFAP), and vertical (GRFV) of the footwear condition Adidas Adistar Boost, color-coded via input relevance scores obtained by Layer-wise Relevance Propagation (LRP). (B–E) Mean GRFs of all test trials as a line plot for one subject, color-coded via input relevance scores for the class obtained by Layer-wise Relevance Propagation (LRP). The grey-shaded areas highlight regions where statistical parametric mapping (SPM) indicated statistically significant differences between the four footwear conditions.
